DQ6: Toggle Bit I

Toggle Bit I on DQ6 indicates whether an Embedded Program or Erase algorithm is in progress or complete,

or whether the device entered the Erase Suspend mode. Toggle Bit I may be read at any address, and is

valid after the rising edge of the final WE# pulse in the command sequence (prior to the program or erase

operation), and during the sector erase time-out.

During an Embedded Program or Erase algorithm operation, successive read cycles to any address cause

DQ6 to toggle. The system may use either OE# or CE# to control the read cycles. When the operation is

complete, DQ6 stops toggling.

After an erase command sequence is written, if all sectors selected for erasing are protected, DQ6 toggles for

approximately 100 s, then returns to reading array data. If not all selected sectors are protected, the

Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are

protected.

The system can use DQ6 and DQ2 together to determine whether a sector is actively erasing or is erase-

suspended. When the device is actively erasing (that is, the Embedded Erase algorithm is in progress), DQ6

toggles. When the device enters the Erase Suspend mode, DQ6 stops toggling. However, the system must

also use DQ2 to determine which sectors are erasing or erase-suspended. Alternatively, the system can use

If a program address falls within a protected sector, DQ6 toggles for approximately 1 s after the program

command sequence is written, then returns to reading array data.

DQ6 also toggles during the erase-suspend-program mode, and stops toggling once the Embedded Program

algorithm is complete.

Table 10.2 on page 68 shows the outputs for Toggle Bit I on DQ6. Figure 10.4 on page 66 shows the toggle

bit algorithm. Figure 16.9 on page 81 shows the toggle bit timing diagrams. Figure 16.10 on page 81 shows

the differences between DQ2 and DQ6 in graphical form. See DQ2: Toggle Bit II on page 66.
